실험 절차

N-Aminoethyl piperazine (0.6 mL, 5.2 mmol) was added to a solution of Example 102j (0.5 g, 1.04 mmol) in methanol (5 mL), followed by the addition of n-tetrabutylammonium iodide (0.075 g, 0.20 mmol) in an atmosphere of nitrogen, in a pressure reactor vessel at 120° C. for 5 h. The reaction mixture was brought to room temperature, concentrated and treated with water. The solid that separated was washed with water, dried, treated with methanolic HCl solution, and refluxed at 70° C. for 2 h. The reaction mixture was concentrated, treated with aqueous sodium bicarbonate solution to neutral pH and extracted with n-butanol. The organic layer was washed with water, dried, concentrated and purified using flash chromatography (silica gel, 20% methanol/chloroform) to obtain the title compound. Yield: 0.075 g, (13%); 1H NMR (DMSO-d6): δ 2.50-2.60 (m, 4H, 2CH2), 2.70 (s, 3H, CH3), 3.00-3.40 (m, 14H, 7CH2), 3.70 (s, 1H, OH), 3.90 (s, 3H, OCH3), 5.20 (s, 2H, CH2), 7.10 (s, 1H, Ar), 7.20 (s, 1H, Ar), 8.10 (s, 1H, Ar), 8.20 (s, 1H, Ar); MS: m/e (EI+) 459 (M+1).
